# Connected Espresso Machine
**Connected Espresso Machine** is a primer on _how to turn "dumb" old coffeemaker/teapot/anything into a smart connected
device_ with a bit of hardware work and programming. For that, a series of [articles](#articles) was written for you to
either have fun or implement your own similar project!
During the implementation of embedded projects, I faced different approaches to code firmware, so in the articles, I
tried to describe _common programming patterns_ that can be accommodated in your hobby projects.
In the current reincarnation, the espresso machine is connected to the home Wi-Fi network and exposes
**[REST API](#openapi)** that is used by the **Web App** to control the espresso machine accessible from the same
network.
**[Web Assets](#web-assets)** (JavaScript and CSS) are served from the **AWS S3 Bucket** and can be updated at any time
without the update of the firmware. While the firmware itself can be flashed _Over-the-Air_ from **PlatformIO IDE**.
While **NodeMCU** is used as a single microcontroller, the implementation is not specific to it and actually, **Arduino
Uno** was used initially to control the AC components of the espresso machine.

## Architecture
### REST
## Hardware
### Controller Board Scheme
### AC Scheme
## Firmware
### Class Diagram
## OpenAPI
Requires [Node.js](https://nodejs.org):
```shell
cd openapi
npm install
npm run build
npm start
```
Open `http://localhost:3000` in browser and explore `openapi.yaml`
## Web Assets
Requires [Node.js](https://nodejs.org):
```shell
cd web-assets
npm install
npm start
```
Open `http://localhost:3001` in browser.
### Test Firmware
```shell
npm run start:test-firmware
```
This will start **Test Firmware** listening at `http://localhost:3002` and sourcing **Web Assets** from
`http://localhost:3001`
Actual **Firmware** can be tested by opening the **Connected Espresso Machine** root page with scripts and styles URLs
overrides in query parameters, like so:
```
http://192.168.1.1:80/?scriptsUrl=http%3A%2F%2Flocalhost%3A3001%2Fscripts.js&stylesUrl=http%3A%2F%2Flocalhost%3A3001%2Fstyles.css
```
Where `192.168.1.1` is *local IP* assigned to **Connected Espresso Machine** and `80` is *HTTP port* configured in
**Firmware**.
